Description

Technical Field

[0001] This utility model relates to the field of leakage current detection technology, and in particular to a rapid detection device for the front of the furnace in electric arc furnace steelmaking. Background Technology

[0002] Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, and N, retaining or increasing beneficial elements such as Si, Mn, Ni, and Cr, and adjusting the proportions between elements to obtain optimal performance.

[0003] In steelmaking, steelmaking furnaces are required. Most steelmaking furnaces currently used are electric arc furnaces. To improve the safety of production, electric arc furnaces need to be inspected before operation. Leakage detection is one of the tests. However, current leakage detection methods can only detect the outer wall and cannot detect the inner wall of the furnace, which can easily lead to missed detections.

[0004] Therefore, it is necessary to provide a rapid pre-furnace detection device for electric arc furnace steelmaking to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a rapid detection device for the furnace front of electric arc furnace steelmaking, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a rapid detection device for electric arc furnace steelmaking, comprising a device body and an electric pen. A base is provided at the bottom of the device body. The device body is electrically connected to the electric pen via a power cord. A counterweight is provided above the electric pen on the outside of the power cord. A grip is provided on the top surface of the counterweight. A support rod is vertically mounted on the top surface of the base. A insertion hole is provided on the top surface of the support rod. An adjusting rod is slidably inserted into the insertion hole. A limit sleeve is provided through the top surface of the adjusting rod. A first mounting seat and a second mounting seat are provided on the top surface of the adjusting rod. A winding wheel is provided inside the first and second mounting seats. The device is equipped with an electric pen, a support rod, and an insertion hole. The coordinated use of the adjusting rod, first mounting base, second mounting base, winding wheel, and counterweight frame facilitates leakage detection of the external and internal parts of the electric arc furnace before its use. During operation, the operator can hold the rod and use the test pen to first check for leakage on the outer wall of the furnace. After the outer wall test is completed, the adjusting rod can be moved upward by the moving plate, so that the top of the adjusting rod is higher than the furnace. Then, by releasing the power cord, and with the action of the counterweight, the test pen is lowered to the inner wall of the furnace and contacts it, thus allowing the test pen to check for leakage on the inner wall. This method is simple to operate, and the movable setting of the adjusting rod and support rod facilitates the use of electric arc furnaces of different heights, improving its operational flexibility.

[0007] Preferably, a winding post is vertically installed on the top surface of the base on one side of the device body. A limiting plate is provided on the surface of the winding post. By setting the winding post and the limiting plate, the operator can wind the power cord around the winding post, which facilitates the subsequent use of a test pen to detect whether there is leakage inside the electric furnace and facilitates subsequent maintenance. Moreover, the setting of the limiting plate facilitates the limiting of the power cord.

[0008] Preferably, the outer surface of the support rod is provided with a slide rail, which is connected to the insertion hole. The bottom surface of the adjusting rod is provided with a movable plate, and a fixing hole is provided through the surface of the movable plate. An adjusting hole is provided on the surface of the support rod. The adjusting rod is fixed to the support rod by fasteners passing through the fixing hole and the adjusting hole. By using the slide rail, fixing hole, and adjusting hole in combination, it is convenient to fix the top position of the adjusting rod after adjustment. During adjustment, it is only necessary to move the adjusting rod upward inside the insertion hole by moving the movable plate. After moving to the designated position, fine adjustment is made to align the fixing hole and the adjusting hole. Then, the fixing rod is fixed by fasteners passing through the fixing hole and the adjusting hole. This method is simple to operate and facilitates the fixing of the adjusting rod.

[0009] Preferably, multiple adjustment holes are provided, and the multiple adjustment holes are equally spaced on the outer surface of the support rod. By providing multiple adjustment holes, it is convenient to adjust the height of the top of the adjustment rod, so that it can be used in electric arc furnaces of different heights and improve its application range.

[0010] Preferably, the inner width of the slide is equal to the thickness of the moving plate. By setting the inner width of the slide to be the same as the thickness of the moving plate, the stability of the moving plate when moving inside the slide is improved.

[0011] Preferably, the base is provided with casters at the bottom, and multiple casters are provided. The multiple casters are installed at equal intervals at the four corners of the bottom of the base. By providing casters, it is convenient to move the device body and make it easy to move the device body next to the electric furnace for testing.

After the outer wall detection is completed, the adjusting rod can be moved upwards by a moving plate, raising its top above the furnace. Then, by releasing the power cord and under the action of the counterweight, the test pen falls to the inner wall of the furnace, making contact and thus detecting leakage. This method is simple to operate, and the adjustment... The movable design of the rod and support rod facilitates the use of electric furnaces of different heights, improving its operational flexibility. With the addition of a winding post and a limiting plate, operators can wind the power cord onto the winding post, making it convenient for subsequent testing with a voltage tester to check for leakage inside the furnace and simplifying subsequent maintenance.

After the outer wall detection is completed, the adjusting rod 8 can be moved upward by the moving plate 18, so that the top of the adjusting rod 8 is higher than the furnace. Then, by releasing the power cord, and with the action of the counterweight 11, the electric pen 13 is lowered to the inner wall of the furnace, making contact with it and thus detecting leakage on the inner wall. This method is simple to operate, and the movable setting of the adjusting rod 8 and the support rod 4 facilitates its use with electric furnaces of different heights, improving its flexibility. The device also incorporates a winding column 3 and a limiting plate. 10. The staff can wind the power cord around the winding post 3, which is convenient for the electric pen 13 to check for leakage inside the electric furnace.

During operation, the operator can hold the handle 12 to move the test pen 13 to first detect leakage on the outer wall of the furnace. After the outer wall detection is completed, the adjusting rod 8 can be moved upwards by the moving plate 18, raising its top above the furnace. Then, by releasing the power cord and under the action of the counterweight 11, the test pen 13 falls to the inner wall of the furnace, making contact and thus detecting leakage on the inner wall. This method is simple to operate, and by using the adjustable rod 8 and support rod 4... The design allows for easy use of electric furnaces of different heights, enhancing its flexibility. By incorporating the winding post 3 and the limiting plate 10, operators can wind the power cord onto the winding post 3, facilitating subsequent testing by the electric tester 13 to check for leakage inside the furnace and simplifying subsequent maintenance. The limiting plate 10 also helps limit the power cord's position. The combination of the slide rail 21, fixing hole 19, and adjusting hole 20 facilitates the fixing of the top position of the adjusting rod 8 after adjustment.
